Bubble

I don’t think this isn’t a particularly "good" image, and it's certainly not an attractive one, but I do find it interesting as it shows something I have never seen before… a fly blowing a bubble of it’s stomach juices! The most likely reason they do this is to cool down (although there are other theories) which says something about the fine weather we’ve been having recently. That said, although this photo was taken around midday, it was pleasantly warm rather than hot.
